Suggestion; once on the 'night shift' stay put for at least three months... Sleep patterns take time to adjust. Jumping between day and night shifts will burn out even the most motivated employee.

> >> Rotating shifts between daytime and nighttime is a horrible thing to >> do to your workers, both for their health and their attention span. > I wonder how well something like the following would work (seen in paid fire/EMS circles): 24 on, 48 off. But staff those 24 shifts with maybe 20% more than actually needed to provide minimum coverage. Of course, that all assumes that you can trust your guys to work out the dynamics of "hey, you watch for the next 30 while I take a break". -c

Configuration Compliance tools??
by Subba Rao 16 Apr '11

16 Apr '11

Hi, I am tasked to analyze the configuration of several Layer 2 Switches for compliance. Most of these switches are from Foundry (now Brocade). What tools are available to perform this task? I could write up a Perl script to parse thru the configuration files. I was wondering if there are some already out there for use. Any information appreciated. Thank you in advance. Subba Rao

Try nipper configuration assessment tool. It provides some very detailed output for many devices though is lacking Juniper support right now. Hopefully Nipper 2 will support JunOS. I haven't used it for Foundry/Brocade yet but they are on the supported device list. http://www.titania.co.uk/index.php?option=com_content&view=article&id=52&It… Regards, Dennis Usle -----Original Message----- From: Subba Rao Sent: Saturday, April 16, 2011 3:39 AM To: nanog(a)nanog.org Subject: Configuration Compliance tools??
